Application November 18, 1931, Serial No 575,787.' Renewed September 2, 1933 13 Claims. (Cl. 120 42) This invention relates to pens. It isparticularly applicable to fountain pens, but certain features of the invention may be applied to other 1 ,5 At present, it is necessary for fountain pen companies to manufacture and stock ten -to fifteen types of pen points to meet the range of present for some pen users to keep on hand at least two different pens, one for fine writing or 15 ledger work, another for ordinary writing or for signatures.

" The present practice makes it necessary for both manufacturers and dealers to carry av large stockof pens, thus tying up quite a large amount 29- of money in stockon hand. The present practice also makes it necessary for the purchaser to try' a number of pens before making his selection.

A general object of thepresent invention is to provide a writing pen which can be readily adjust-ed for'diflerent widths of ink line and difierent rates of ink flow. 7

Another object of the invention is to provide a writing pen having means to adjust the set of the nibs.

A further object of the invention is to provide a fountain pen in which the feed bar is held closely against the pen point.

1 is a plan view of a fountain pen em-' bodying a preferred form of the invention. Fig. 2 is an enlarged plan'view of the forward end of the pen shown in Fig. 1.

Fig. 3 is a greatly enlarged section taken on line 33 of Fig. 2. 1

Fig. 4 is a sectional exploded view correspond- 4qg ing to Fig. 3.

Fig. 5 is an exploded view corresponding to Fig. 2.

Fig. 6 is a detail plan view showing a modified form of the invention. Fig. '7 is a detail longitudinal section showing a second modification of the invention.

Fig. 8 is a detail longitudinal section showing a third modification of the invention.

Reference will now be had to Figs. 1 to 5 inclugsive. The pen designated as a whole by 1 has the usual barrel 2, which is adapted to contain a supply of ink. From the end of the barrel there projects a feed bar 4 and a pen point designated as a whole by 5. From the under side of the feed 55, ibar, there is inserted a tapered annular bushing 6,

which isinteriorly threaded and preferably made 1 of metal. A small screw 7, having ataperedhead portion, passes through the pierce Qfthepen point and a portion ofthe feed bar and then engages the threaded lbushing 6; By tightening 0 down the screw '7 pressure is applied. tending to. separate or vary the set of nibs 8, 8. By theset of the nibs is meant the tendency of the nibs. to'hug one another.

It will be apparent that'thescrew '7 may be ad juste'd to vary the set of the nibs over quite a wide range, whereby'the flow of ink,-and the width of the line' whicl'i the pen will make, will be correspondingly varied. It is'not necessary in all cases to adjust thescrew 'Tso-that'thetipsm of the nibs will be separated when the penis off the paper. Byapplyinga pressurewith screw '7 which merely'tendsto separate the nibs, the. nibs will 7 more readily separate, when "the point is applied to the paper. Hence, a wider line and higher rate of ink flow will'be obtained than when no pressure is applied by screw '7. The" feed bar' 'is provided with two feed channels 9, 9 on opposite sides of the screw 7, and 'the two channels meet' at 10. Thus the screw 7 does not interfere with the flow of ink} 1 In the form of the invention shown in Fig. 6, the set of the nibs is varied by a small turnbuckle 15, the arms of which are welded, soldered, or otherwise secured to the nibs. With this form 5 of, the invention, a double channeled feed bar (as in Fig. 5) may be used, but an ordinary single channel feed bar maylikewise be used. i r v In the form of the invention shown in Fig. 7, e an adjustment screw 11 operates in a manner similar to the adjusted screw in the first formof the invention, but engages a block .12 suitablyv secured to the upper side'of the feed bar as by molding the feed bar about it. Space is provided at 13 for ink flow beneath blockl2.

In the form of the invention shown in Fig. 8, an adjustment screw 14 is operable from beneath the feed bar and has a conical end which engages the under side of the pierce of the pen. In this 7 form of the invention, the pierce engaging end 1 of the adjustment screw is preferably enlarged to prevent removal; and the screw is assembled with respect to the feed bar before the feed bar" and the pen point are assembled together. Preferably, the feed bar is of a double channeled type similar to that shown in Fig. 6.

It'is very desirable that the feedbar should be at all times in close contact with the pen point, because otherwise the film of ink will break, thus interfering with the flow. The ordinary practice in assembling pens is to heat the feed bar and bend it, so that it contacts with the pen point. This practice does not always produce satisfactory results. In the forms of the invention shown in Figs. 2 and 7, the adjustment screw, in addition to adjusting the set of the nibs, draws the pen point and the feed bartogether, thus insuring contact at all times between the pen point and the feed bar.

It will be apparent that the present invention greatly simplifies the manufacture and sale of pens in that a stock of only three or four different pen points may be carried; and the purchaser may readily adjust the point to his'own hand,

writing. Also, the user may readily adjust his pen for diiferent types of work, thus making it unnecessary for him to purchase more than one pen.

The present invention may be embodied in forms other than those particularly disclosed and hence the foregoing disclosure is merely illustrative in compliance with the patent statutes and is not to be considered as limiting.

I claim: V

1. In a pen, a pen point having nibs, and adjustable means carried by the pen operativeto exert on the nibs a force tending to separate them. from one another.

2. In a pen, a pen point having nibs, and adjustable wedging means operative to exert on the nibs a force tending to separate the same.

3. In a pen, a pen point having nibs, a feed bar, and means exerting a force on the nibs tending to separate them from one another, said means also being operative to urge the pen point toward the .feed bar.

4. In a pen, a pen point having nibs and a pierce, and an adjustable screw having a tapered portion engaging the pierce to vary the set of l the nibs.

5. In a pen, a pen point having nibs and a pierce, a feed bar, said feed bar having a threaded aperture, and a screw passing through the pierce and engaging said threaded aperture, the

screw having a tapered portion which engages the pierce to vary the set of the nibs.

6. In a pen, a pen point having nibs and a pierce, a feed bar, said feed bar having a threaded aperture, a screw passing through the pierce secured to the nibs, and adjustable separatingmeans cooperating with the first means and operative to exert on the nibs different magnitudes of force tending to separate them from one another.

8. In a pen, a pen point having nibs, and a turnbuckle secured to the point and operative to vary the set of the nibs.

9. 'In a pen, a pen point having nibs, a feed bar having two feed channels, and means passing between the channels and operative to exert on the nibs a force tending to separate the same.

10. In a quill type pen, a pen point having nibs, adjustment means secured to each'nib and. extending across said nibs and adjustableto act as a tension member to control the spread of the slit between the said nibs.

11. In a quill type pen, a pen point comprising nibs,'adjustable means connected with each nib and comprising a tie member extending across said nibs and adjustable to restrain the separation of said nibs when writing pressure is applied to the point of the pen. I

12. In a quill type pen, a pen' point having nibs, an adjustable member connected with each nib and being adjustable to control the spread of said nibs relative to each other.

13. In a quill pen, a pen point having nibs, an.

adjustable member is secured to each nib and bridging the slit between said nibs and being adjustable'to control the effective width of said slit during writing operations.
